Step-by-step explanation:

Quotient rule,

$a {}^{n} \div a {}^{m} = a {}^{n - m}$

Do this,

a^(n-3)=a^9

Since the exponents have to be the same, this turned into a simple one step equation:

n-3=9

+3 +3

**n = 12, so the final answer is 12.

Kyle plays softball. His goal is to have a batting average of .400 or greater by the end of the season. The ratio that relates t

gregori [183]

Answer:

The number of hits is $T \ge 30 \ hits$

Step-by-step explanation:

From the question we are told that

The ratio of the number of hits to the number of chances is equivalent to the batting average

The number of chances is j = 65 + 10 = 75

The number of hit so far is n = 25

Generally the batting average can be represented mathematically as

$A = \frac{n + k}{ j}$

Here k is the number of additional hits Kyle need to get in order to obtain the batting average of 0.40 or more

$\frac{25 + k}{ 75} \ge 0.40$

=> $k \ge 5 \ hits$

Hence the number of hits for Kyle to get a batting average of 0.400 or greater by the end of the season is

$T \ge k + n$

=> $T \ge 5 + 30$

=> $T \ge 30 \ hits$
